To all whom it may concern:

Be it known that 1, WILLIAM HUGHES, a citizen of the United States,residing at Taunton, in the county of Bristol and State ofMassachusetts, have invented certain Improvements inEyeleting-Machines,of which the following description, in Connectionwith the accompanying drai'vin gs, is a speoi fica tion, like referencecharacter-son the drawings indicating like parts in the several figures.

This invention relates to machines for set ting fasteners such aseyelets insheet material and one of its objects is to provide animproved machine by the use of which blind or invisible eyelets may beset the uppers of boots and sh'oes- In setting invisible eyelets in ashoe'npper' the outer part of the upper is perforated and the eyeletsare set in a part of the Min-- ing, or facing stay which is stitched tothe lining, in register with the holes so punched. In the finished shoe,therefore, nothing is visible but a series of perforations through whichthe lacing passes; These perforations are relieved from the strain ofthe lacing and kept from pulling out of shape by the invisible eyeletsset in the material directly beneath them. k v

In machines for setting blind of invisible eyelets it is customary toemploy a combined punching and feeding tool to perforate both portionsof the upper and then feed the upper by the punched hole. While theeyelet is being set in one part of the upper the other part is pushedupwardly upon the tool where it will be out of range of the settinginstrumentalitiesi I have discovered that it is important to limit themovement of this part of the upper upon the tool, as the tool must bepromptly withdrawn at the conclusion of the s'ettingopeia tion and itswithdrawal is delayed if the part of the upper is passedupwardly uponthe tool farther than isneessary. An iinportant feature of the presentinvention eon-1 sists in means for limiting the movement upon thepunching tool of the part of the upper in which the eyelet is not set.

As herein shown a thin separating meniher is employed to separate thatpart or the upper which is to be pinched only from that part which istobe pnn'ched and eyelete'd. Another feature of the invention consistsin means for supporting or reinforcing the Work separating member duringthat part of the cycle of the machine when this member would otherwisebe likely to become bent or distorted. An advantage resulting from theemployment of such su -s porting means isthat the separating member maytake the form of plate and may be made thinner than otherwise so thatits insertion between the layersof the work is' facilitated.- Theemployment of athin plate rendersit possible to locate the upsetting dieand set the eyelets close upto a line of top stitching. This improvesthe accuracy of the work and also permits the employment of the machinewith less disturbance to the usual stitching room system than would bethe case if it' were necessary to eyelet the upper before it had beentopstitched.

Aks herein shown the same element is utilized for limiting" the upwardmovement of the shoe upper part upon the punching and feeding tool andfor supporting the work separating member, but itwould be within thescope of the invention to employ distinct elements for thesedifferentfunctions.

While the supporting and limiting means maybe of any desiredconstruction; in the illustrated embodiment of the invention, theirfunctions are supplied by a part of the presser foot; This is anadvantageous con struction because it utilizes parts of themachinealready available, economizes space and positions the suppo'rting'means; properly with respect to the Work separating plate. Thisconstruction; accordingly, constitutes stillanoth'er' feature of theinvention;

These and other features of the invention will behest understood andappreciated from the following description of a preferred eInbodiifientthereof selected for" purposes of illustration and shown in theaccompanying dr wings,- in which Figure 1 is a view in perspective of somuch of the" Ina-chine as is neees'sary' te understand its operation;

having invisible eyelets set therein.

-The invention is herein shown as embodied in an eyeleting machine ofthe type disin Letters Patent of the United States No. 686,928, grantedNovember 19,

1901. As in the machine of said patent,-

the transversely movable head 2 carries a punch 4 which is arranged tobe forced downwardly against a cutting block 6 toperforate the .work andthen to be moved laterally to feed the punched work into alinement withthe setting dies. The lower setting die 8 is arranged to pick off thelowermost eyelet in a raceway and carry it upwardly inserting its barrelthrough the perforations in the work.

Secured to the work table 6 is a thin projecting plate 10 which carrieson its lower face the upsetting die 12, the latter being disposed inalinement with the path of the lower die 8. The die carrying plate 10 ismade of thin material and the thickness of the die itself is reduced toa minimum, so that it may be easily inserted between two partiallyattached layers of sheet material, such as the lining and theouterportion of a shoe upper, without disturbing their normal superposedrelation; The plate is provided with a longitudinal slot 11 whichextends from a point above the cutting block 6 toward, but not to, thesetting position. The die carrying plate is offset between the ends ofthe slot 11 so as to permit the end of the punch, when moving in thefeeding operation, to pass out of the slot 11 and just clear the back ofthe plate. noted that a portion of the punch remains in the hole in theouter layer of'material while the eyelet is being set in the under Thisis advantageous because the work is thus held positively againstdisplace ment and a perfect registration of the hole with the eyelet isinsured. At its extreme end the plate 10 is provided with a pair ofoppositelyextending projections or cars 14.

.The machine is provided with a loopshaped presser foot 16which isrigidly secured to theupper end of a vertical rod 18 normally urgeddownwardly by a stiff compression spring 20 so that the presser foot isheld yieldingly' against the work and on the table 6." Secured to thelower side of the presser foot adjacent to the setting pos1- tion is aplate 17 recessed at one side or m'adeU-shaped to accommodate the punch'and disposed with its sides overlying-the ears 14 of the plate 10. Onepurpose of the 7 plate 17 is to reinforce the die carrying plate 10 atpoints adjacent to' the settingposition,

this being also the point-at which the punch is retracted from thework.j Anotherpur It will be pose of the plate 17 is to limit the movementupwardly upon the punching tool of the outerportion 32 of the shoequarter.

' After the setting operation the plate 10 acts as a stripper for thepunch by holding down the lining and incidentally the outer portion ofthe quarter which is stitched thereto when the punch is elevated.

A pivoted arm 22 is provided at the rear of the work table 6 and isequipped with an edge gage 28 by which the distance of the eyelet fromthe edge of the work is determined in the usual manner. The arm 22 isconnected beneath the table 6 to a hand lever 24 by which the edge gagemay be swung forwardly or rearwardly to vary the spread of the eyeletsfrom the edge of the lacing slit.

In operating the machine the shoe quarter is positioned on the worktable 6 with the lining 30 and attached stay, if one is used, beneaththe die carrying plate 10, and the outer portion 32 of the quarter abovethe plate 10. The point at which the first eyelet is to be set beinglocated beneath the punch, the machine is set in operation. The punchdescends passing through the slot 12 and perforating both the lining andouter portion of the quarter and then moves later- .ally drawingthelining along the lower side of the plate 10 and the outer portion ofthe quarter along its upper surface. The punch A remains in theperforation in the outer portion of the quarter throughout the feedingand setting operation but the lining is moved downwardly off thepunch-when it encounters the downwardly bent portion of the plate 10.The feeding movement of the punch ceases when the perforation in thelining has been brought vertically above the lower setting die, the endof the punch remaining in touch with the back of the plate 10 above theupsetting die 12. At the end of its feeding movement the punch ispartially surrounded by a recessed plate 17. The lower die 8 is thenelevated forcing the eyelet through the perforation in the lining andclenching it againstrthe upsetting die 12 while the latter is backed upby the punch reaching in through the hole in the outer part of thequarter. about the same time the presser foot, which has been elevatedduring the feeding movement, is lowered upon the work." The punch isthen moved upwardly while the plate '10, which is necessarily flexibleon account of its extreme thinness, is maintained in position and heldinitial position whereupon the' cycle ofoperationsmay be repeated.

Having thus described my invention, 1
